after flame goes out the igniter will not glow for about 25 minutes and then it will glow and light and flame with flame shutting down after 5-10 again
Hi.
You will have to check for continuity :
the flame sensor, cycling thermostat, hi-limit thermostat.
When the dryer fails unplug it and using the multimeter check those parts for continuity.
Here are the breakdown diagrams and http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5172909
Thank you. Post the results.
